Face Blocks[1] are blocks that appear in Super Mario Bros. Deluxe's Vs. Game and You vs. Boo modes. At the start of the stage, they appear as White Face Blocks[2], which are smiling, and in later stages, cause certain Dotted Line Blocks to become solid white blocks that help the player, before changing into Red Face Blocks[2], which have their tongue sticking out and cause most Dotted Line Blocks to become solid red blocks that generally block the way. Jumping into a Red Face Block causes it to turn into a white one, turning all of the solid blocks back into Dotted Line Blocks for a few seconds before both automatically revert back; the player can also hit a White Face Block to instantly turn it back into a red one.
